They might, for example, see only a headline, or perhaps a headline, summary, and a thumbnail photo.

A search for the television show "Lost" brings up results for the show and also a thumbnail photo for each character.

例如搜索剧集《迷失》，搜索结果会同时显示搜到的视频和剧中人物的缩略图。

When a user clicks a thumbnail, have the larger version of the thumbnail (not the thumbnail itself) replace the current main photo.

当用户点击缩略图的时候，要用较大的缩略图(不是原缩略图)替代当前的主图。
